AH Her needs observations now
These days are critical for observations of AH Her - please try to observe it and report your observations to the AAVSO International Database. The astronomers really need to see how the minimum interval evolves optically and when the minimum actually occurs, particularly because AH Her is behaving erratically, for correlation with their spectroscopic and optical data. AAVSO Alert Notice 483 has details.
Many thanks and good observing - Elizabeth Waagen
